scope:

This standard presents guidelines for establishing minimum requirements to ensure proper application and performance of a field-applied coal tar enamel (CTE) system to the external surfaces of pipe. Included are methods for qualifying and controlling the quality of a CTE system, guidelines for its proper application, and inspection and repair techniques to ensure its long-term performance.

This standard is applicable to CTE coating systems used to prevent corrosion in conjunction with cathodic protection.

This standard complements the discussion of plantapplied CTE pipe coating systems in NACE Standard RP0399.
